 **Crane**: Crane is the newest and most powerful HCC resource . If you
 are new to using HCC resources, Crane is the recommended cluster to use
 initially.  Limitations: Crane has only 2 CPU/16 cores and 64GB RAM per
-node. If your job requires more than 16 cores per node or you need more
-than 64GB of memory, consider using Tusker instead.
+node. CraneOPA has 2 CPU/36 cores with a maximum of 512GB RAM per node. 
+If your job requires more than 36 cores per node or you need more than
+512GB of memory, consider using Tusker instead.
 
 **Tusker**: Similar to Crane, Tusker is another cluster shared by all
-campus users. It has 4 CPU/ 64 cores and 256GB RAM per nodes. Two nodes
-have 512GB RAM for very large memory jobs. So for jobs requiring more
-than 16 cores per node or large memory, Tusker would be a better option.
